Non-corrosive conductive concrete material and power transmission line tower grounding foundation
The invention relates to the technical field of power transmission line tower grounding devices, in particular to a non-corrosive conductive concrete material and a power transmission line tower grounding foundation. The non-corrosive conductive concrete material is prepared from the following raw materials in parts by weight: 100 to 150 parts of cement, 50 to 75 parts of coarse aggregate, 50 to 75 parts of fine aggregate, 50 to 90 parts of fly ash, 50 to 120 parts of water, 40 to 70 parts of conductive filler, 2 to 5 parts of water reducing agent, 3 to 5 parts of rare earth, 1 to 5 parts of bentonite composite material and 0.5 to 3 parts of additive. The inorganic conductive particles and the stainless steel fibers are compounded to form a main conductive doping phase, the water reducing agent, the rare earth, the bentonite composite material and the auxiliaries are added, the fluidity and compactness of mortar and the conductivity and mechanical strength of the conductive concrete can be effectively improved, the resistivity of the conductive concrete is smaller than or equal to 0.015 omega.m, the compressive strength is 45-50 MPa, and the breaking strength is 6.5-7.5 MPa.
